A Sovtek Green Russian
circuit with an added "Creamy Dreamer" mod, this pedal
produces a more hi-gain fuzz tone than stock muffs. The Dreamer
was once widely believed to be the "Siamese Dream" tone.
While that assertion has since been disproved (Corgan actually performed
on a stock 1977 opamp version - see our I.C.B.M.) it remains one
of the most popular muff mods ever. By grounding emitters of the
two gain stage transistors, the level of fuzz and sustain is increased
substantially and this remains hugely popular with grunge, alt blues
and garage-rock guitarists alike.
